A radiocarbon-dated gelifluction lobe in the Nachvak Fiord area, northern Labrador, Canada
  • A radiocarbon-dated gelifluction lobe in the Nachvak Fiord area, northern Labrador, Canada
  • Radiocarbon dates obtained on organic materials overriden by a gelifluction lobe allow some estimate of past gelifluction rates for a site near sea level in northern Labrador. The calculated mean gelifluction rate for the last 400 years
  • is in the order of 8 mm/yr, somewhat higher than the average gelifluction rate described from other locations in the Canadian Arctic. The lobe contains two lithostratigraphic units : an inner diamicton, probably representing a buried gelifluction lobe, overlain
A model for variations in gelifluction rates with temperature and topography: implications for global change
  • A model for variations in gelifluction rates with temperature and topography: implications for global change
  • Active layer ; Climatic warming ; Cold area ; Europe ; Gelifluction ; Global change ; Meltwater ; Model ; Northern Europe ; Rill wash ; Scandinavia ; Slope dynamics
  • A model is proposed for gelifluction rates, in terms of active layer depths and sub-surface runoff. It has been applied, using a global database of monthly climate, to estimate regional variations in gelifluction rates under current conditions
  • , and with both increases and decreases in mean temperatures. It is concluded that wide bands, roughly between 40-65°N and S, should have experienced a period of very intense gelifluction during the postglacial warming.

  • Neoglacial gelifluction in the Jostedalsbreen region, western Norway : evidence from dated buried palaeopodsols
  • Radiocarbon dating of thin palaeopodsols buried beneath turf-banked gelifluction lobes at four localities in the low alpine mountain zone in the Jostedalsbreen region, show that gelifluction processes were initiated subsequent to the late Subboreal

  • Current processes of gelifluction and fluvial sediment transfer have been monitored for several years in the periglacial altitudinal belt of the southern Hohe Tauern mountain range, central Alps Austria. A close connection between cryogenic
  • processes and the destruction of vegetation cover, the intensity of gelifluction and also the amount of sediment transfer in the headwater channels can be demonstrated. Through a combination of these results with a data on Holocene slope, soil and channel

  • Geomorphic processes are most active above timberline (ca 1 500 m a.s.l.) involving downslope transfer of rock and sediment and periglacial processes of patterned ground, stone-banked terraces, gelifluction lobes and thufurs. - (DWG)
Relationship between ground ice and solifluction : field measurements in the Daisetsu Mountains, Northern Japan
  • of soil moisture and ice segregation. Seasonal freeze-thaw cycles produced both frost creep and gelifluction. In layers shallower than 60 cm, ice segregation during the freezing season induced seasonal frost heave, and ice melt at the same depths during
  • the thaw season promoted gelifluction as well as seasonal frost creep. At greater depths, gelifluction did not occur even when the thaw plane reached the ice-rich layers. The results at the study site demonstrate that segregated ice plays an important role
  • in gelifluction, but only at shallower depths.

Preliminary results of investigations on some periglacial phenomena on King George Island, south Shetlands
